To aZZ whom it may concern:

Be it known that I, SAMUEL T. Locnwoon, a citizen of the United Statesof America, re siding at Chicago, in the county of Cook and State ofIllinois, have invented certain new and useful Improvements inBran-Packers or Packers for Packing Bran and other Articles, of whichthe following, in connection with the accompanying drawings, is aspecification.

In the drawings, Figure 1 is a side elevation of a packer embodying myimprovements. Fig. 2 is a bottom view of the packing-cylinder, showingthe parts applied thereto. Fig. 3 is a sectional detailrepresenting amodification of construction. Fig. 4: is a section in the plane of theline .1 x of Fig. 1, viewed in the direction indicated by the arrowthere shown. Fig. 5 is a section in the plane of the line x x of Fig.1., viewed in the direction of the arrow there shown. Fig. 6 is asectional detail of the lower part of the packing-cylinder, and showingthe parts therein and connected thereto. Fig. 7 is a section in theplane of the line 1/ 7 of Fig. 4; and Fig. 8 is a sectional detail ofthe packing-box and the parts therein, and also showing the position ofthe packiugcylinder with relation thereto at the completion of the workof packing.

Like letters of reference indicate like parts.

A represents a strong frame. B a block having a central circular openingwhich is screw-threaded, as indicated in Fig. 7. This block is rigidlyattached to the frame A, or may form a part thereof.

C is a hollow or tubular screw or fced'tube fitted to and working in theblock 13.

D is a initcred cog-wheel, through which the screw C passes. In thescrew C are longitudt nal grooves a a, one or more; and a CL are ribsprojecting from the hub of the wheel D into the grooves a u. The wheel Drests and turns freely on the block I3.

C may be termed a downward extension or continuation of the hollow ortubular part C; and b b are clasps or lugs engaging an annular rib orshoulder, Z), at or near the lower end of the part C, as is clearlyindicated in Figs. 1, 6, and 8. These clasps or lugs are firmly attachedto the part C, and the latter is thereby connected to the screw C insuch a manner that the latter may be rotated with out rotating the partC, while the latter will move up and down with thesaid screw as it israised and lowered.

E is a rod or cross-bar attached at its ends to the screw 0, and E isarod depending from the bar E. I The part E, as indicated in Fig. (3, isarranged within the screw 0 and located at or near its lower end, andthe part I l eX tends down into the part 0.

F F are wings (two or more) extending radially from a central part orhub, through which the pendant passes freely. The outward ends of thewings F F are rigidly at tached to the part C by means of rivets orotherwise, as is indicated at c c, Fig. 6.

G is an augerlike device applied rigidly'to the lower end of the rod E.

H is a shalt turning in a hanger, H, and

ing the wheel I). J is a pulley or belt-wheel on the shaft H.

In practice I make provision for rotating the shaft H in reversedirections, alternately, and also for varying the speed of its rotation;l but as such gearing is common and well known I have not here shown thesame nor described it with particularity; furthermore, it does notconstitute a part of my invention, as any suitable driving gearing maybe employed.

K is a box,which in the example shown is square, or nearly so. This boxImake in two rectangular pieces, (I. d, hinged to each other along onecorner, as indicated at 1, and adapted at the diagonally-opposite cornerto be temporarily clasped or clamped together, as indicated at c, mypurpose being so to construct the box that it will be strong and capableof being opened with facility forthe removal ofthe bag, as willhereinafter more fully appear, and any well-known or suitable details ofconstruction which will permit the box being so opened may be employed.

L is a box arranged directly above the box K, and there suspended bymeans of cords f f, running over pulleys depending from the upper partof the frame A. The lower end of the box L may be flanged, shown at gg,for the purpose hereinafter referred to. The said box also projectssomewhat below the said flanges, so as to enter the upper end of the boxK. a little way when the box is arranged in the position indicated inFig. 1. The box Ii may be termed a detachable we having on one end amitercd pinion, I, engag- 7 tension upward of the box'K. As the boxesare square, attention is called to the fact. that the lower end of thepart is flanged, as shown at 71 in such a manner as to meet or nearlymeet the sides of the boxes.

M is a bag arranged in and fitting the box K, and N N are removable,thin, and smooth metallic plates arranged within the bag.

0 is a plate or block arranged next below the flange h, as shown in Fig.8, and P is a piece of cloth arranged below the plate 0.

R is a feed hopper or funnel entering the upper end of the screw 0. y

In Fig. 3 I'have shown a modification rep resenting the box L, withsides of such length as to allow them to project into the box K, so

that the'said projecting parts will perform the functions of the platesN N. When employing this form of construction there should be roomenough between the top of the box L and the head of the frame A topermit the upper box to be withdrawn upward from the box K, for thepurpose hereinafter explained.

To use this machine for the purposes for which it is adapted, I proceedas follows: I place a suitable bag in the lower box, the latter beingclosed and fastened, and in the bag I arrange the plates N N, or the boxL, when the latter is constructed or extended, as shown in Fig. 3. Ithen set the machine in motion, running the driving-gear in such adirection as to carry the lower end of the tube 0 down to the bottom ofthe bag. I now feed the bran in through the hopper R, the bran of coursefilling the tube 0, and being fed in as may be required. The movement ofthe machine is then reversed-in other words,it is so run that the screw0 will be raised while being rotated. As the flange h is square and fitsinto the box or between the plates N N, the part 0 will not turn withthe screw, but will move up and down with it, owing to the manner inwhich the screw and part 0 are connected to each other. The wings F F,therefore, do not turn or rotate. The augerlike device G on the lowerend of the bar E, rotates with the screw 0, for the reason that the barE, from which the bar E depends, is attached to the said tube. By thismeans the bran will be forced out through the augerlike device into thebag, and be firmly pack d therein, it being understood that the plates NN are only expedients to hold the bag open properly and to prevent thebran from pushing or drawing the bag down in the manner hereinafter morefully explained. The Wings F F, of which there may be any suitablenumber, prevent the bran from being whirled next above the device G. Ifeed the machine and allow it to run until the bag and also the box Lare packed full. After that I stop feeding, but allow the screw 0 tocontinue moving upward until I can place the plate 0 next underneath theflange h and the cloth 1 next under the plate 0. I now reverse thedirection of movement of the screw 0, which will then move down andpress the bran in the box L into the bag. Now, by opening the box K, andraising the box L, and removing the plates N N, the cloth 1? may besewed to the bag, so as to serve as a top therefor. Then, on raising thescrew 0, the bag may be removed. I find that a very large amount of branmay thus be packed and pressed into a comparatively small bag, theamount in a bag of given'size being much greater, as I believe, than bymeans heretofore in use.

The machine, as is obvious, may also be employed with advantage forpacking and pressing other materials or substances.

I am aware that bran has heretofore been packed by being fed through anauger-like device on a solid shaft and rotated in a bag; and I desire tostate that I do not here intend to be restricted to any particular meansfor holding or retaining the bag, nor to the supplemental extension ofthe bag-holding box.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-- 1. A packer adapted for feeding andpacking the bran or other material by means of a rotative tubular screwor feed-tube turning in a screw-threaded bearing and carrying anauger-like device for ejecting and compress-- ing the bran or othermaterial.

2. The combination, in a packer, of a rotative tubular screw orfeed-tube, an augerlike device in connection with and carried by thesaid tube, a fixed screw-threaded bearing for the said tube, and adriving or rotating wheel splined to the said tube.

3. The combination, in a packer, of a rotative tubular screw orfeed-tube, a fixed screw-threaded bearing for the said tube, a tubularextension clasped to the lower end of part of the said tube and capableof turning thereon, the wings F F, carried by the said extension, andthe auger-like device G, carried by the said feed-tube, substantially asand for the purposes specified.

4. The combination, substantially as specified, in a packer, of therotative tubular screw or feed-tube O, carrying an auger-like device, G,and having therein one or more grooves or channels, a a, the fixed blockor screwthreaded bearing B, the wheel D, having therein one or moreribs, a or, entering the said groove or grooves, and a rotary driver orpinion, I, engaging the wheel D, for the purposes set forth.

In testimony that I claim the foregoing as my own Ihereto affix mysignature in presence of two witnesses.
